WRENCH.

To all whom it may concern:

Be it known that we, WILLIAM F. Pnonsr, CHARLES E. ELSASS, and JOHNLOUIS ELSASS, citizens of the United States, residing at Chillicothe, inthe county of Ross and State of Ohio, have invented certain new anduseful Improvements in Wrenches, of which the following is aspecification.

\' This invention relates to wrenches and it is particularly designed toconstruct a wrench adaptable for attaching fish plates adjacent to railjoints, said wrench having an attachment whereby the bolt may beretained within said fish plates and rail, while being operated upon bythe wrench.

A further object of this invention is the provision of means whereby theattachment heretofore referred to, may be retained away from the boltduring the placement of the Wrench upon the nut.

It also contemplates the pro-vision of a means which will be simple androtatably operable whereby the wrench may be operated in either of twodirections, or whereby the handle of the wrench may be made inoperativewith respect to the nut engaging portion thereof.

With the above and other objects in view, this invention consists in theconstruction, combination and arrangement of parts, all as hereinaftermore fully described, claimed and illustrated in the accompanyingdrawings, wherein:

Figure 1 is a central vertical section of a wrench constructed inaccordance with the present invention, parts thereof being in section,the dotted lines illustrating the position of the bolt retainingattachment when the same is retained in an elevated position, Fig. 2 isa section taken on the line 22 of Fig. 1, Fig. 3 is a section taken onthe line 33 of Fig. 2, Fig. 4 is a perspective view of a keeper adaptedto lock said bolt engaging attachment, and, Fig. 5 is an outsideelevation of the nut engaging member.

The wrench forming the subject matter of the present invention,comprises a handle having a hearing at its lower terminal, said bearinghaving rotatably mounted therein a tubular nut engaging sleeve ormember, said member having a series of ratchet teeth formed in the outersurface thereof. A socket is formed adjacent to the lower terminal ofthe handle and upon one side thereof, said socket having reciprocatinglySpecification of Letters Patent.

and rotatably mounted therein a spring actuated plunger or pawl, saidplunger or pawl having its lower terminal beveled and adapted to engagethe teeth formed on the nut engaging sleeve. Means is provided at theupper terminal of the socket whereby the pawl may take any one of threepositions, thereby permitting the wrench to operate in either of twodirections, or permit the handle to rotate about said sleeve withoutimparting a motion thereto. An L-lever or hell crank is pivoted in thehandle and extends transversely therefrom, said L-lever carrying at theouter terminal of its horizontal arm a vertical rod, which has at itslower terminal a swiveled bearing which engages the head of the boltbeing operated upon. A keeper is reciprocatingly mounted upon the handleand engages the other termin al of the bell crank or L-lever forretaining said swivel bearing in its operative position.

Reference being had more particularly to the drawings, 10 indicates arail of the usual and standard construction having the fish plates 11disposed on each side thereof, said fish plates and rail being piercedby the bolt or bolts 12. A tubular nut engaging sleeve 13 is adapted toengage the nut 14 operating on the outer terminal of the bolt 12 and isof any suitable construction, said sleeve being provided with a seriesof substantially centrally arranged ratchet teeth 15. A bearing 16 isrotatably mounted on the outer terminal of the sleeve 13 and is'retainedthereon through the instrumentality of a screw 17 piercing said bearingand engaging a circular groove 18 formed in the outer terminal of thenut engaging sleeve 13. A normally vertical handle 19 is formed on thebearing 16 and is adapted to operate the nut engaging sleeve 13 ineither of two directions. In order to provide a means whereby thismotion may take effect, a socket 20 is formed on the handle 19 adj acentto the lower terminal thereof and is disposed directly above the teeth15., The upper terminal of the socket 20 is reduced and is adapted toreceive the shank 21 of the plunger 22 which operates in the enlargedportion of said socket. A spring 23 is interposed between the shoulderof the ment with the teeth. One side of said plunger is beveled in orderto permit the ready passage thereof over the teeth upon the recovery.The upper end of the socket 20 is provided with the oppositely disposeddepressions or recesses 24 and the outwardly extending depression 25.hen the arm 26 carried by the shank 21 of the plunger is retained in thedepression 25, the lower end of the plunger is retained from engagementwith the teeth 15, but when the arm 26 is located in either of theopenings 24, the plunger engages the teeth 15 for the operation. of thesleeve 13 in either of two directions.

An opening 27 pierces the handle 19 directly above the socket 20 and hasdisposed on each side thereof the bracket 28. An l lever or bell crank29 is pivotally mounted between the arms of the bracket 28 and thehorizontal arm of which projects over the rail, while the vertical armnormally extends parallel. to the handle. A sleeve 30 is reciprocatinglymounted on the horizontal arm of the bell crank 29 and carries adependent arm or rod 31 which is provided at its lower terminal with thebearing 32. A spindle 33 is rotatably mounted in the bearing 32 andcarries at its inner terminal the curved bearing 34 which engages thehead of the bolt 12and retains the same in its inoperative position. Thesleeve 30 is retained in its various positions upon the horizontal armof the bell crank or L-lever 29 through the instrumentality of a screw35 piercing said sleeve and bearing against said arm.

A keeper 36 is reciprocatingly mounted on the handle 19 and is providedwith an auxiliary keeper 37 which engages the vertical arm of the bellcrank or L-lever 29 and retains the same flush against the handle. Astop 38 is provided adjacent the upper terminal of the handle 19, toretain the sleeve thereof, while a similar stop 39 is formed on the bellcrank or L-lever 29 to prevent the keeper from descending below adesired point. In order to retain the L- lever in an elevated position,while the nut engaging sleeve is being placed upon the nut 14, a lip 40is formed on the auxiliary keeper 37 and engages the semi-circularrecess 41 formed on the inner edge of the bell crank. From thisconstruction, it will readily be seen that the keeper 36 may be raised,allowing the vertical arm of the bell crank 29 to swing away from thehandle 19, after which the keeper may be dropped upon said handle, thelip 40 engaging the semi-circular recess 41 and wedging said bell crankaway from the handle and retaining the same in this position.

In the usual construction of railroads, the fish plates which areadjacent the heads of the bolts, are provided with ellipticalenlargements about the openings in which said bolts are placed, whilethe bolts are provided with a similarly formed enlargement 42 adjacentthe head thereof, which is re ceived within the elliptical openings inthe fish plates. This construction is to prevent the bolts from beingturned, while the nuts are being removed. It has been found, however, inactual practice, that after removing the bolts, with the ordinary wrenchthat has been heretofore used, the wrench, after the nut has beenloosened to a certain extent, will push the projection 42 from engagement with the elliptical opening in the fish plate. It is thereforeunderstood that by using a wrench with the attachment illus tratedherewith, the bearing 34 in conjunction with the arm 31 prevents theprojection or enlargement 42 from being pushed by the wrench fromengagement with the elliptical opening formed in the fish plate.

We do not intend to limit this wrench to use on railroads and the like,as the same is adaptable to bridge construction and all structural steelwork. Furthermore, the details of construction may readily be changedwithout interfering with the spirit or use of our invention.
